Answer:

(-4,-1) is the answer unless your asking for an actual equation

Answer:

x=2

Step-by-step explanation:

Combine like terms, add 8 to both sides of the equation, simplify, divide both sides by the same term, simplify

Answer:

x = 2

Step-by-step explanation:

1. Combine like terms

15x - 8 - 3x = 16

1 2  −  8  =  1 6

2. Add  8  to both sides of the equation

1 2  −  8  =  1 6

      +8   +8

3. Simplify

12x = 24

12x/12 = 24/12

x = 2

Answer:

7 x 4 + 7 x 9, 7(4+9)

Step-by-step explanation:

Answer:

12 is the complete length and 10 is the number of sides

12x10= 120

Answer:

3.     P = 48 units   A = 116 units²

Step-by-step explanation:

A = 12 x 12

= 144

Now we can subtract the missing areas. 4 x 4 = 16 and 6 x 2 = 12.

144 - 16 - 12

= 116 units²

P = 12 + 12 + 12 + 12

= 48 units

(1, -4)

You could just count the units

Answer:

$396

Step-by-step explanation:

The total cost of the patio = area of the patio x cost per square yard

area of the patio = area of a rectangle = length x breadth = 11 x 9 = 99 yards^2

total cost of the patio = 99 x 4 = $396

Answer:

−4x−6

Step-by-step explanation:

Distribute the Negative Sign:

=2(x+2)−x+3(−x−2)+−1(2x+4)

=2(x+2)+−x+3(−x−2)+−1(2x)+(−1)(4)

=2(x+2)+−x+3(−x−2)+−2x+−4

Distribute:

=(2)(x)+(2)(2)+−x+(3)(−x)+(3)(−2)+−2x+−4

=2x+4+−x+−3x+−6+−2x+−4

Combine Like Terms:

=2x+4+−x+−3x+−6+−2x+−4

=(2x+−x+−3x+−2x)+(4+−6+−4)

=−4x+−6

Answer:

-4x - 6

Step-by-step explanation:

2(x+2)−x+3(−x−2)−(2x+4)

Distribute the Negative Sign:

=2(x+2)−x+3(−x−2)+−1(2x+4)

=2(x+2)+−x+3(−x−2)+−1(2x)+(−1)(4)

=2(x+2)+−x+3(−x−2)+−2x+−4

Distribute:

=(2)(x)+(2)(2)+−x+(3)(−x)+(3)(−2)+−2x+−4

=2x+4+−x+−3x+−6+−2x+−4

Combine Like Terms:

=2x+4+−x+−3x+−6+−2x+−4

=(2x+−x+−3x+−2x)+(4+−6+−4)

=−4x+−6

Answer:

0A + B = 3AB

10 / B = 3 - (1/A)

10/B is between 2 and 3.

B = 5, A = 1

you just need to do this but i dont know

Answer:

#1 s=-133/5

#3 a. b=-4

#3 b. x=23.45

#3 c. p=201

Step-by-step explanation:

#1 −5(s+30)=−17

Step 1: Simplify both sides of the equation.

−5(s+30)=−17

(−5)(s)+(−5)(30)=−17(Distribute)

−5s+-150=−17

−5s−150=−17

Step 2: Add 150 to both sides.

−5s−150+150=−17+150

−5s=133

Step 3: Divide both sides by -5.

−5s−5=133/−5

s=−133/5

#3 a. [tex]-\frac{1}{2} (b-6)=5[/tex]

Step 1: Multiply both sides by 2

[tex](-\frac{1}{2} (b-6))(-2)=5(-2)[/tex]

Step 2: Simplify

b-6=-10

Step 3: Add 6 to both sides

b-6+6=-10+6

Step 4: Simplify

b=-4

#3 b. 0.4t(x-0.45t)=9.2

Step 1: Divide both sides by 0.4

[tex]\frac{0.4t(x-0.45t)}{0.4} =\frac{9.2}{0.4}[/tex]

Step 2: Simplify

x-0.45=23

Step 3: Add 0.45 to both sides

x-0.45+0.45=23+0.45

Step 4: Simplify

x=23.45

#3 -4(p-212)=44

Step 1: Divide both sides by -4

[tex]\frac{-4\left(p-212\right)}{-4}= \frac{44}{-4}[/tex]

Step 2: Simplify (there is way more to this step than I am putting)

p-212=-11

Step 3: Add 212 to both sides

p-212+212=-11+212

Step 3: Simplify

p=201

Answer:

x = -8

Step-by-step explanation:

9/4 = (x-10)/x

Cross multiplying,

9x = 4(x - 10)

9x = 4x - 40

9x - 4x = -40

5x = -40

x = -40/5

x = -8

Answer:

A. 5.4 in

Step-by-step explanation:

At the top of the line segment GH, you can see it ends on Circle D's circumference. Therefore, if you made a line segment from D to G, its length would be the radius. Lines DE and GH are perpendicular and make a 90 degree angle, so you can make line DG a hypotenuse, use pythagoreans theorem, and find the radius. However, since they intersect at a halfway point, you have to divide 10 and 4 by 2. 10/2 = 5  4/2 = 2   5^2 + 2^2 = r^2

5^2 = 25 and 2^2 = 4, so 29 = r^2. The square root of 29 is 5.385, or 5.4 inches.

Step-by-step explanation:

Answer:

Prism A: 264; Prism B: 265.125

Step-by-step explanation:

✔️Surface area of the triangular prism = base area + Perimeter*Height of prism

Base area = ½*bh

b = 6 cm

h = 8 cm

Base area = ½*6*8 = 24 cm²

Perimeter of base = 6 + 8 + 10 = 24 cm

Height of prism = 10 cm

Surface area of the triangular prism = 24 + 24*10 = 264 cm²

✔️Surface area of rectangular prism = 2(LW + LH + HW)

L = 5.25 cm

W = 5.25 cm

H = 10 cm

Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)

= 265.125
